Yeah, it's funny to hear people complain "I hate reruns, no more reruns!" Except, the show only has 26 episodes or so in a season. ("24" has 24, obviously.)
So you can go with the "we're gonna run consecutive episodes all the way through the season" option, like "24" does... but that means you go 28 weeks (or more, depending on whether two episodes air in a single night), 7 whole months, between seasons.
Or, you can do runs of new episodes, with reruns or other shows airing during the gaps.
Personally, with the advent of DVRs, I don't really care how they do it. My DVRs record the show and I watch it when it's a new episode.
